A, hydrolysis of feather powder equipment
The new hydrolysis of feather powder machine developed by our company, is based on the advanced techniques and reference of the European and American countries, combined with the new productdevelopment and production experience for more than 20 years of my company. It adopts hydrolysis of high temperature and high pressure,strong shear conditions, advanced processes, special equipment. Its outstanding characteristic is the complete destruction of the spatialstructure of feather keratin, so it has by the food industry waste intoanimal feed products can fully digest the soluble protein absorption, to achieve turning waste into treasure. According to the authoritative department repeatedly test the average rate of digestion absorption rate can reach more than 75%.
The whole set of equipment with water separator, feather feather, featherwringing machine feeder, belt conveying machine, hydrolysis tank, buffer bin, screw conveyor, steam dryer, rotary cooling sieve, grinder,quantitative packing machine, gas condensation system and an electric control cabinet deodorant.
Two, the product yield of 10000 products: General feather feather powder 500kg.
Three, mainly focus on the modification of equipment and technology in the following aspects:
1, to adapt to the rapid increase of hydrolysis, increase the heat transfer area, the same type of equipment is increased by about 40% or so, but did not increase the size of the equipment, the equipment covers an area of and the same number of prototype.
2, the increased heat transfer capacity per unit area, which improves theheat transfer coefficient of K, the K value from the original 50--60kcal/ atabout h square meters, now increased to 75kcal/ square meters of about h DEG C. We take the heating surface in a modified self purificationdevice, the material around the center offset to the heating surface, the heating surface is distributed uniformly in the body, increasing agitationand other measures.
3, in order to improve the compressive capacity of the equipment,equipment modification in multiple compression weak links are improved,eliminate or weaken the vast majority of stress concentration region,pressure parts to improve the stress state. The main PRESSUREPARTSselected 20g, 16MnR, 20c and other quality of boiler and pressure vesselheating confined by steel plate, improve the safety and applicability ofequipment.
4, in order to improve the shear stress on the feathers and mesh of keratin protein, in the internal structure of the new equipment has taken a number of measures, one is the increase of stirring leaf number, two is to change the mixing blade shape, three is the use of fixed teeth andincrease the relative speed of some measures for tooth interphase structure is greatly improved, improved shear conditions.
Through the above measures, the product quality and the production efficiency has been significantly improved. Mainly in:
The cystine content of 1, the product increased significantly, up to 1.5 times the acid hydrolysis of feather powder. The digestion rate increased significantly, under the optimal conditions, the product of amino acid digestibility reached 41 - 80%, and the rate of gastric digestion products(PDP), amino acids, soluble protein efficiency (PDAA) (PS), amino acid content, bulk density (BD) and other indexes were improved remarkably.
2, has the auxiliary operation time is shortened, the steam utilization rate is high, significantly high thermal efficiency, can save steam according to the measured about 6%.
3, because of rapid heating, uniform, stable, stable product quality.
